About 0WWQ8YZ

0WWQ8YZ is the ICD-10-PCS code for a revision procedure on the respiratory tract using a via natural or artificial opening endoscopic approach with other device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to other operations on thorax, the ICD-9-CM procedure title it maps to (34.99).

For a different body part, codes include 0WWP8YZ (gastrointestinal tract) and 0WWR8YZ (genitourinary tract).

The same procedure with a different approach is coded 0WWQ0YZ (open), 0WWQ3YZ (percutaneous), 0WWQ4YZ (percutaneous endoscopic), 0WWQ7YZ (via natural or artificial opening) and 0WWQXYZ (external).

With a different device, use 0WWQ81Z (radioactive element) and 0WWQ83Z (infusion device).

It is an operating-room procedure in the MS-DRG logic for DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC), DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Respiratory System O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
